New BP hasn't accepted a meal in 3 weeks.

Right there. I've never heard a good reason to feed a BP in a separate feeding enclosure.

I handle BP feedings as almost religious ceremonies. Only at night, total silence in the house, dim lighting, nobody but myself, minimal distractions. Once the snake bites and coils, all lights go out and I leave the room. BPs need to feel secure to eat.

I do the same thing lol.

Also try to make the prey warm when you're offering it as they can be uninterested if they don't detect enough heat. I blast my thawed mice with a hairdryer on hot for about 10-20 seconds before offering and if the snake refuses I re-warm the mouse with the hairdryer and try again. Some people have also recommended just leaving the mouse outside the hide for a few hours and coming back later since some BPs are too nervous to eat when you're there.
